Hi,<br><br>I made thechanges and when I run it from the command line window I get a message which is says that png supports unsigned char and unsigned short. But when I make these changes I get failures in the building of the project:<br>
<i>error C2440: 'initializing' : cannot convert from 'itk::Concept::Detail::UniqueType_bool<__formal>' to 'itk::Concept::Detail::UniqueType_bool<__formal>'. </i>Could somebody help me with this?<br>
<br>Thanks in advance<br><br><br><div class="gmail_quote">2011/3/15 robert tamburo <span dir="ltr"><<a href="mailto:robert.tamburo@gmail.com">robert.tamburo@gmail.com</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
